RAILWAY-CROSSING STOP.

Application filed July 7, 1924.

To all whom it may concern:

Be it known that we, ERRAL OLIVER PRES- NnLL and SAMUEL AUSTIN PRESNELL, citizens of the United States, residing at Algiers, in

the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in a Railway-Crossing Stop, of which the following is a specification.

This invention relates to new and useful improvements in means for causing vehicles to stop before crossing a railway crossing.

One of the important objects of the present invention is to provide a railway crossmg stop wherein the same includes the provision of obstructions in the highway adjacent the opposite side of the rails whereby vehicles will be caused to stop before encountering the same, thus warning the driver of the vehicle of the fact that a railroad crossing is about to be approached.

Another important object of the. invention is to provide a railway crossing stop of the above mentioned character, which will at all times be positive and efficient in carrying out the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification in which like numerals designate like parts throughout the same:

Figure 1 is a top plan view of a railway crossing showing our improved invention in the highway.

Figure 2 is a side elevation thereof, and

Figure 3 is a sectional view taken approx: imately on line 3-3 of Figure 1.

In the drawing whereinfor the purpose of illustration is shown the preferred embodiment of our invention, the numeral 1 designates generally the railway crossing,

the rails being illustrated at 2 and the highway or road at 3 in the drawing. Extending transversely across the highway or road 3 on each side of'the rails 2 and at a suit able distance-therefrom is the obstruction 4. The obstruction 4 is preferably formed of concrete and sloped upwardly as illustrated at 5 in the drawing and the upper edge thereof is slightly rounded as shown at 6.

The obstruction is of such height as to extend above the highway or road 3'sufficiently to cause a vehicle to stop when the obstruction or trap is encountered by the vehicle.

Serial No. 724,627.

Arranged adjacent the highway 3 on each side of the rails 2 at a suitable distance from the obstruction 4 is a warning sign 7 which is readily visible. X

It has often been experienced that a driver of a vehicle is unaware of the fact that a railway crossing is about to be approached and as there is usually nothing to prevent the vehicle from passing over the crossing in numerous places, serious accidents often result from such cases. The provision of an obstruction such as is shown and .above described, on each side of the railway crossing will cause a vehicle to be brought to a stop before the railway crossing is encountered, thus indicating to the driver of a vehicle that he is about to approach a railway crossing'and thereby further causing the operator of the vehicle to drive cautiously. The obstruction is adapted to extend across the full width of the highway so that there will be no possibility of a vehicle not passing over'the same and the provision of'a rounded upper edge on the trap to prevent any injury to the tires of the vehicle.

A railway crossing stop of the above mentioned character, wi at all times be positive and efficient in carrying out the purposes for which it is designated and will prevent numerous accidents caused by vehicles speeding over a railway crossing.

While we have shown the preferred embodiment of our invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing frgm the spirit of the in vention and the scope of the appended claim.

Having thus described the invention, what we claim is z A warnin device adapted to be located cross road including an upwardly extending projection disposed across the road a distance from the railroad track and made of the same material as the cross road, said projection being in the form of an isosceles triangle in cross section thereby providing oppositely climbing sides, the upper edgeof the projection being rounded.

In testimony whereof we aflix our signatures.
